### Hamid is viewing an image of a bird produced by a set of concave lenses. What must be true about the image? a) It is a virtual image. b)It is upside down. c)It is larger than the actual bird. d)It is capable of being projected.

The correct answer is option b, that is, it is upside down.

A concave lens refers to a lens, which exhibits at least one surface that curves inwardly. It is a diverging lens, that is, it disperses out the rays of light, which have been refracted via it. A concave lens is thinner in the middle in comparison to its edges and is used in the correction of myopia.

If the concave lens is used to observe the image of the bird, then the image will possibly be observed upside down.

### Brock brings a magnet near a metal object. a magnetic force acts on an object, pulling it upward. which of the following best describes the magnetic force? a) frictional force b) contact force c) gravitational force d) a force that acts at a distance

Explanation:

Magnetic force is the force which acts from one charged object to another charged or neutral object.

This force acts at a certain distance and if the charged objects are oppositely charged then they attract each other. When the charged objects have same charge then the objects repel each other.

Thus, we can conclude that a force that acts at a distance best describes the magnetic force.

### Which statement about the half life of a radioactive sample is true? a.) it is an exact measure of the decay of an individual atom. b.) it measures the tendency of a radioisotope to decay radioactively. c.) it is affected by the concentration of the radioactive substance that is present. d.) it can be calculated based on neutron number.

The radioactive decay can be expressed through the following exponential law:

If [A]₀ is the initial concentration of the radioactive nuclei and [A] is the concentration after a decay time t, then:-

[A]/[A]₀ = exp(-kt)

or, k = -1/t * ln[A]/[A]₀ ----(1)

where k = decay rate constant

Now, the half life is given as :

t1/2 = 0.693/k ----(2)

Thus, the half life is dependent on k which is in turn dependent on the concentrations, [A] and [A]₀

Ans: c) it is affected by the concentration of the radioactive substance that is present.

### The volume of a gas is always the same as the volume of __________. its container the atmosphere its atoms its molecules

Explanation:

There are three states of matter:

Solid state : In this state, the molecules are arranged in regular and repeating pattern. The molecules are closely packed that means they are fixed and thus have fixed shape and volume.

For example : Copper

Liquid state : In this state, the molecules are present in random and irregular pattern. The molecules are closely packed but they can move from one place to another.  They have fixed volume and take the shape of the container.

For example : water

Gaseous state : In this state, the molecules are present in irregular pattern. The molecules are not closely packed and they can move freely from one place to another and spread out.  Thus they do not have any fixed shape and occupy the whole volume of the container.

For example : Helium gas
